which pads for 996 GT3?

[andye30m3]

Recently bought a 996 GT3 with Performance friction discs and pads and don't really think their ideal for what I'm using the car for. I tend to find they sound horrible when being used hard and the brake dust makes a mess off the wheels. The noise alone puts me off using them in anger even though I'd told it's down to the pad compound

I've got the original front discs so was looking to take the PF stuff off, what pads to people recommend for fast road maybe the odd gentle track day?

I found the standard discs and pads ( pagid yellow ) were more than up to the task of fast road use. The did squeal a little when cold but after you get some temp into them they're great.

Certainly no squeal from my Pagid RS29s with a dollop of copperslip on the back of them, they last ages but so they should at £400+ for fronts.
Has anyone tried Ferrodo 3000 compound?
There is a huge thread on rennlist about the fact that Cayenne S discs are a 350mm bolt on ( ATE parts ) for 996 GT3. The cost is tiny compared to say Alcons, I just wondered if the ATE Ferrodo combination would be a significantly lower cost option for trackies. I appreciate you would not get the longevity of Alcon Pagid.

If you have a lift of those cayenne ones you might rethink that approach They're made out of stone.

Some good info from slippy here

The Ferodo DS 3000 is a superb compound, lots of bite, excellent performance at high temps, but the brake dust residue will ruin the paint finish on your wheels (and left on there becomes almost impossible to shift) but it will also get onto your cars bodywork and wreak havoc on that too. It is a true race compound (Prodrive specced it for the upgraded Alcon BBK on the Impreza P1) Soon after owners started to complain about damage to their wheels and paintwork and they reverted to the DS2500, which has nothing like the initial bite or high temp durability.

Stick with the standard OPC supplied P90 compound Pagids or RS29s.

Another one happy with Pagid RS29s here.

What's in the pads that causes the corrosive residue on the Ferrodos, I remember fitting Perf Friction 97 compound on my old 3.2 and it was hell to get the dust off the wheels?

PS thanks for the advice, I have MK1 sport design wheels and they are a pig to clean at the best of times.

I suspect that as they're semi metallic they have some copper in them as the deposits they left on the wheels were copper coloured .


Semi-metallic pads get their name from their composition. Each friction pad contains a substantial amount of metal. Common ingredients are steel wool, iron, or copper, mixed with fillers, friction modifiers, and lubricants such as graphite. On the plus side, these pads have higher operating temperatures than organic pads, draw heat out of the rotors, and do not wear as quickly. On the other hand, they’re more abrasive and tend to wear rotors more quickly, make more noise, produce heavier dust. Most race pads on the market today are semi-metallic.

Because the constituent materials, tools, and processes involved are more expensive than those used to produce organic pads, semi-metallic pads are more expensive.


They are superb pads, I had them in an Impreza 22B that was as quick as an E39 M5 and a 360 Modena up to 120 leptons. The brakes were epic (four pots and 330mm discs) but a couple or so weeks into my ownership, I noticed that the deposits being left on the wheels were rock hard and were etched into the paint finish. No matter what I used to clean them, I couldn't shift it.

I think RS 29s are just as good but without the downsides. Just be aware that RS29s are more hydroscopic than most pads, left outside through the winter, they'll turn to water laden blocks that will provide little or no retardation against even lightly corroded discs.

If the car's mainly used on the road and with only occasional track use, then that sounds squarely like the usage Porsche will have developed their standard factory fit pads for. You'll only get the std pads too hot on a track day if you're either a novice and breaking far too much or very experienced and breaking very hard. If it's the former, stick with std and have a little tutoring. It's not the latter, as if it was you'd not care about dust and noise on the road!!
